APPARATUS' FOR IMPARTING MOTION.

SPECIFICATION forming partof Letters Patent No. 689,454, dated December24, 190'1. Application filed .Tuly 17, 1900. Serial No. 23.907. (Nomodel.)

To alt whom it may concern,.-

Be it known that I, WILLIAM HENRY BAX- TER, a subject of the Queen ofGreat Britain and Ireland, residing at Knapping Mount, Walker road,Harrogate, in the county of York, England, have invented a new anduseful Improvement in Means or Apparatus for Imparting Motion to VariousKinds of Machinery, of which the following is a specifi, cation.

This invention relates to improvements in means or, apparatus forimparting motion -to various kinds of machinery; and it is particularlyapplicable to that class of machines in which a swinging orreciprocating portion thereof is actuated from a rotating shaft. It mayalso be adapted so as to be interposed between rotating portionsthereof.

The objects of my invention are, first, to provide means whereby thedriving-shaft and parts connected therewith employed for actuatingthemoving part of the machine may be mounted in bearings forming part of orrigidly xed in advance of or in the rear of such moving part, so asto'move therewith; second, to utilize the-weight of such actuating partsfor increasing the power without any appreciable or detrimental loss ofmovement, and, third, to dispense with the additional use of suspensionlevers or chains or intermediate toggles and parts connected therewith.I attain these objects by the mechanism illustrated in the accompanyingdrawings, which I desire to be taken as typical or illustrative examplesof the means employed for carrying the invention into practice.

In the drawings, Figure lshows a front elevation of the mechanism forimparting motion to a machine with one of the fly- Wheels removed. Fig.2 shows a plan of the mechanism shown in Fig. l looking at the underside. Fig. 3 shows a part elevation of a modified form of the apparatus,and Fig. 4L shows a plan vieuT thereof.

Similar characters refer to similar parts throughout the several views.

K A is the swinging or reciprocating portion, which in the drawings isshown as a pendent lever and is hereinafter termed the lever A, and Bthe shaft or vspindle upon which the lever A is mounted and fixed orupon which it is hung, so as to swing freely thereon. In either case thelower end is free to reciprocate. The shaft is carried in bearings B',formed in or fixed to the framework of the machine. Y

In advance of or at the rear of the lever A is or are cast or otherwiseformed or rigidly fixed thereon, so as to move therewith, one or morearms or projections C. Two of such arms are shown in the drawings, andthey are hereinafter termed the arms C. Abearing D, with or without thecap or cover E, is either formed in the outer end of each arm or adjustably fixed thereto. When an adjustable bearing is employed, it may bein the form of a pedestal or block D, having a cap E and arranged, asshown in Fig. 1, to slide in guides on the upper surface of the arms Cand to be fixed in position thereon by plates F and adjusted by screwsG.-

His the driving-shaft, which is mounted in the bearings D of the arms C.On the shaft H is or are mounted and fixed one or more driving-pulleysI, {Iy-wheels J, and eccentrics K. In the drawings only one eccentric isshown at or about the center of the driving-shaft H, and it may beformed, if so desired, on the shaft H. Motion may be imparted to thedriving-pulley from any suitable source of power by ordinary means.

,Upon the eccentric K a connecting-rod L is pendently mounted. While itis preferred to mount only one connecting-rod upon a single eccentric,yet, if so desired, two or more eccentrics may be employed for each ofsaid rods. I'Vhen more than one connecting-rod is used, then a separateeccentric is employed for each connecting-rod. Instead of making theconnecting-rod L as shown, it may be made in skeleton form, with an eyeor bearing at each end to receive the shaft H and the trunnions or shaftM. v

The lower end of the connecting-rod L or at a suitable distancetherefrom is armedv on each side thereof with a trunnion M, or a shaftmay be arranged to pass through the connecting-rod and to project oneach side thereof to form the trunnions, or the trunnions may be formedon or out of, as shown in the drawings, a separate block N andadjustably secured to the lower end of the connecting-rod by the nut O,as shown.

P represents toggle-levers arranged in the drawings on each side of theconnecting-rod L; but, if so required, the connecting-rod may be soarranged that only one set of toggle-levers may be used, or the numbermay be increased, as circumstances require. The inner ends of each setof the toggle-levers are mounted on one ofthe trunnions M, which formsthe pin or fulcrum for jointing them together. The hole in which thetrunnion works may be, though not necessarily so, en-

larged, as shown in the drawings, for receiv` ing a bush Q. The outerends of each set of toggle-levers are respectively attached to the leverA and to a pedestal R, capable of being ixed to the framework of themachine or a stationary portion thereof or to lugs formed thereon.

S is a rod for connecting the lower end of the lever A to the part ofthe machine to be actuated.

It will be readily understood that the same movement of the lever A maybe obtained by mounting a shaft l on the arms C in place of thedriving-shaft H, as shown in Figs. 3 and 4. On the shaft 1 is or arefulcrumed and fixed one or more double-ended levers 2. The drivingshaftH', with the pulleys I', flywheels J', and eccentric K', mounted thereonis carried in the bearings 7, arranged ata suitable distance from, aswell as below or above, the levers 2, so that the eccentric will acteither directly on the outer end (or ends) 3 of said levers or, as shownin Figs. 3 and 4, the ends-3 of lever (or levers) 2 are connected to theeccentric-strap 4 by one or more suit'- able levers or rods 5. To thefree and inner end 6 of said lever 2 is connected a pendent rod L', towhich the inner ends of the togglelevers P are attached, as previouslydescribed.

As an illustration of the application and action of the above mechanismit is shown applied to, say, a rotating disk or body T, mounted on ashaft U, as shown at Fig. 1. By pendently mounting the driving-shaft Hin the bearings D of the arms C, forming part of or rigidly attached tothe lever A, the whole weight of the ily-wheels J, pulleys I, andconnecting-rod L, which is mounted, as previously described, upon theeccentric K on shaft H, is utilized for imparting and increasing thepower of the lever A, from which the power or pressure is given od.Further, the connection of the toggle-levers P with the connecting-rod Lnot only assists in supporting the latter, but also aids in retaining itin position, and thereby dispensing with the use of suspension-chains ordraw-back rods and intermediate toggles. When the shaft H is caused torotate and the eccentric K is at its highest point, as in the drawings,then the toggle-levers P will by their connection to the saidconnecting-rod and to the lever A and pedestal R be simultaneously drawnupward and straightened, thus causing the lever A to swing or turn onits supporting-shaft and its lower end to be moved forward for actuatingthe disk T and reciprocating it in the direction of arrow 8 but when theconnecting-rod is caused to descend it will carry with it the inner endsof the toggle-levers, and the disk T will then be caused to rotate.

The speed at which the disk T revolves is controlled by the speed atwhich the drivingshaft is made to rotate and is also regulated by thethrow of the eccentric and the difference between the centers of thepoint of suspension of the leverA and that of the driving-shaft H androd S at its connection to the lever A.

The herein described motion -imparting mechanism may be adapted to avariety of machines, such as for punching, shearing, brickmaking, andpumping, also windmills, bicycles, and the like.

It will be observed that the levers P are pinjcinted to theconnecting-rod L, the pendent lever A, .and the fixed pedestal R andthat they serve to support, sustain, and operate the pendent lever A.The levers P operate the pendent lever A in both directions.

Having now described the nature of this invention, what I claim, anddesire to secure by Letters Patent, is-
